Due to its wide available spectrum and excellent optical performance, single-mode optical fiber G.652D is the best choice to support a variety of applications such as Ethernet, Internet Protocol (IP), Asynchronous Transfer Mode (ATM), Synchronous Optical Network (SONET), and Wavelength Division Multiplexing (WDM). Fiber provides more bandwidth for backbone, metropolitan area and access networks.
Fiber meets or exceeds ITU-T Recommendation G.652D and IEC 60793-2-50 type B1.3 fiber specifications.
Designed to operate across the entire spectral range of 1260-1625 nm, providing 50% more usable wavelengths for increased transmission capacity
Excellent optical performance supports high-speed transmission technologies such as DWDM and CWDM
Being compatible with existing 1310 nm equipment
Good protection and excellent strip force stability
Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
